Fixed Inductors are a wide ranging family of electro magnetic devices or components most commonly used in electronic equipment. The ILSB0805ER3R3K is part of them; it is a surface mounted device (SMD) chip used for a variety of applications. 

This chip is composed of two coils which are wound around a ferrite or iron core. The coils are usually connected in series or parallel and their geometry, along with the number of turns and the core material, determines the inductance, the impedance, the Q factor, the sensitivity, and the temperature coefficient.

This chip in particular has an inductance range of 3.3 uH, which is rated at 24 mA (with an internal resistance of 2.1 Ohm). This device also has an excellent power capability of 1.5 Watts at 70°C. It exhibits high stability of the inductance value against temperature and current changes, and low heat generation. 

One of the principal applications of this chip is the filtering of high frequencies from a signal. This is done by connecting it to a capacitor where a circuit is constituted allowing only the frequencies wanted to pass, while blocking the unwanted ones. These kind of circuity is also named highpass, lowpass, or bandpass filters. 

The ILSB0805ER3R3K can also be used to create balun transition, which allows the transformation of balanced signals to unbalanced ones, or the response adjustment of frequency amplifiers, oscillators, and mixers.

Switched-mode power supplies (SMPS) also use the ILSB0805ER3R3K as one of the major constituents. Here, the inductance helps to decrease the voltage and create transistors with alternating currents (AC). 

Moreover, this component can be used to create Self-oscillating mixers or as a Noise Filter, which helps to reduce high frequencies and protect electrical and electronic circuits from noise.

The ILSB0805ER3R3K chip is the ideal choice due to its compact size and high power handling. It is a very good option for low-current, large-signal, and high-frequency applications, and this chip can operate from -55°C to +125°C, and should be mounted on FR4 substrate. The package is an 8-pin package which has two pin rows (one connected to the ground and the other to the load).
